Phone or Chat OnePlus
Tell them some shit excuse like it's not charging
 
Make sure to make it seem urgent like you have a job that relies on it
 
When they say it'll take 7-10 days say that it's too long or whatever and that your gonna get fucked if you don't have access to a phone by x day
Sometimes they'll give you an advanced replacement and then there you go easy phone I guess?
